LV8804FV Functional Description

VCTL
The gradient and limit current are determined by the resistance of the RF pin.
Minimum speed
This minimum speed is determined by the MINSP pin voltage.
0.5A
The current flowing to the motor and the control characteristics are determined by adjusting the resistance of the RF
resistor.
By connecting a resistor with a resistance of 0.25
between the RF pin and GND, the limit current is set at a motor
current of 1A, and the control characteristics shown in the diagram above are achieved.
By increasing the RF resistance, the limit current is reduced; conversely, by reducing the RF resistance, the limit
current is increased.
Since IO max. is 1.2A, the RF resistance must be set in such a way that the current flowing to the motor does not exceed
this maximum value.
By varying the CTL voltage between 1V and 3V, the current flowing to the output is limited.
PWM control is exercised within the voltage range above (1V to 3V) to control the motor speed.
When the CTL voltage is less than 1V, the current limiter value determined by the RF resistance is reached, and the
motor speed is limited.
When the CTL voltage is greater than 3V, PWM is reduced to 0%, and the motor stops. (However, the motor does not
stop if the minimum speed has been set.)
The minimum speed can be set by resistor-dividing the REG voltage (5V) to create a voltage of 1V to 3V, and inputting
this voltage to the MINSP pin.
If the minimum speed is not going to be set, the MINSP pin and CTL pin (pin 8) must be short-circuited.

SOFTS pin
The gradient changes in accordance with the capacitance of the SOFTST pin.
(The higher the capacitance, the steeper the gradient.)
